Goal of the study was to investigate nutrient uptake, growth and yield of the cabbage (Brassica oleracea var. capitata) variety'Atlas-70'as influenced by the application of different organic fertilizers. Randomized complete block design (RCBD) comprising five treatments with three replications were executed to conduct the study. Treatments were T Absolute control. Results of the experiment showed that the same amount of N, P, K and S from cow dung, poultry manure and vermicompost showed significant differences (P≤0.05) on plant height, unfolded leaves, head circumference, marketable yield, total yield and nutrient content in cabbage. Organic fertilizers (cow dung, poultry manure and vermicompost) resulted better nutrient uptake as compared to the chemical fertilizers. However, vermicompost tended to be the potential organic source for higher yield and nutrient uptake of cabbage and thus is suitable substitute of the most commonly used nitrogen (urea) sources for the production of cabbage.

The effect of green manure and nitrogen fertilizer applications on rice performance and post-harvest nutrient status of the soil was studied at the Regional Wheat Research Station of Bangladesh Agricultural Research Institute (BARI), Shyampur, Rajshahi, Bangladesh. The experiment comprised two sets of treatments: (i) green manure application (Crotalaria jusncea, Sesbania aculeata, Sesbania rostrata,Vigna radiata, and Phaseolus mungo) and (ii) application of different nitrogen levels (0, 40, 80, and 120 kg ha −1 ). Both treatments had a significant effect on the growth and yield of transplanted aman (T. aman) rice. We show that soil fertility can be maintained and rice yield can be improved through incorporation of green manuring and nitrogen fertilizer management. Green manure and nitrogen management generated positive responses in important morpho-physiological traits such as leaf area index (LAI), specific leaf area (SLA), crop growth rate (CGR), leaf relative growth rate (LRGR), leaf weight ratio (LWR), and net assimilation rate (NAR), which may result in a greater contribution of yielddetermining traits and eventually higher grain yield. The results indicate that all green manures in combination with higher N levels accelerate SLA, LWR, LAI and CGR. Better performance of potential yield-contributing characters and relatively higher nitrogen uptake and higher N and protein content in grain and straw were found in combination with all green manure and higher N level treatments. An increasing level of post-harvest soil nitrogen content was observed with the application of higher levels of nitrogen in combination with green manures. Therefore, green manuring in combination with judicial nitrogen fertilizer management is deemed necessary for sustainable T. aman rice cultivation.

Because of using sulphur free fertilizer, rice crop facing tremendous sulphur (S) deficiency throughout the world as well as in Bangladesh. However, farmers of Bangladesh often overlook the importance of sulphur fertilization on rice yield. Therefore, the present study was conducted to investigate the influence of different levels of sulphur on growth, yield attributes and uptake of N, P, K and S by grain and straw of BRRI dhan41 rice variety. The experiment was laid out in randomized complete block design with three replication and eight treatments including control. The result of the study revealed that the highest plant height, panicle length, filled grain was found in T1 (50% RFD of S) treatment, while the utmost number of effective tiller and straw yield was recorded in T5 (150% RFD of S) treatment. Interestingly, maximum grain yield as well as uptake of N, P, K and S by grain and straw was significantly higher in T6 (175% RFD of S) treatment. The highest grain yield of T6 treatment might be due to maximum nutrient use efficiency. However, in all cases control treatment (T0) gave the worst result. The present study clearly indicates that higher rates (175% of the recommended dose) of S along with other fertilizers may be recommended for better growth and yield of BRRI dhan41 in Bangladesh soil.
